The PATTI® is a Pneumatic Adhesion Tensile Testing Instrument. The Quantum Series is a new line of portable adhesion testers with an updated look and feel.
Features
Four models available, Analog, Digital, Gold and Concrete (includes accessories for concrete coatings testing)
Quantitatively measures the adhesion strength of numerous coatings, including paints, polymers, ceramics, inks, films, adhesives, and thermal or arc-sprayed metals
Great for laboratory or field use
Simplified design requires fewer internal parts and reduces the frequency of maintenance/repair
The reduced number of internal parts makes the it lighter and more portable than other PATTI®'s
The test surface can be smooth, rough, porous, flat or curved
Can also be used to test the strength of adhesives under non-room environmental conditions from 32-212 degrees Fahrenheit (0-100 degrees Celsius)
All pistons are self-aligning
Patented piston design assures uniaxialalignment with the pull-stub axis for "true tensile testing"
New regulator eliminates the internal pop valve, allowing for use of entire air cartridge
New air cartridge capacity is twice that of other models
The powder-coated box is robust and will maintain its aesthetic value
With the exception of the new, higher capacity CO2 Cartridge, you can use the same pistons, pull-stubs, and supplies as previous PATTI®'s
There is a different piston for each load range, it is recommended that you choose the piston whose midpoint testing range is closest to the suspected tensile strength of your coating. For instance, suppose that your coating has a tensile strength near 1000 psi. You would choose the F-2 piston option. Although the F-8 piston could test a coating in this range, it would be on the lower end of the range of the F-8. At least 100 psig supply pressure (up to 150 psig) is required
Certified calibration and accessories for testing adhesives are available
Custom-machined pull-stubs are available at any size, either flat or with a radius to match curved surfaces
The Digital and Gold Models display maximum load on a 4-1/2 digit seven-segment display gauge with 0.5% accuracy. They also display the increasing load, and hold the maximum psig value when the Min/Max button is pushed. Simply push Zero/Clear in order to zero the readout and you are ready for the next test.
The PATTI Quantum GOLD Model also features:
Real-time transmission of pull-tests via USB and the included netbook
A LabVIEW®-created software package developed specifically for the Gold Model - eliminates the need for charts. Pre-installed on the included netbook
Computer generated reporting capabilities in HTML - suitable for immediate posting on your server to share pull-test results around the world instantly
USB camera attachment and associated software to photo document your pulls

Procedure
The PATTI® Quantum uses compressed inert gas to apply a continuous tensile load to an aluminum pull-stub which is bonded to the test surface with an adhesive.
After the adhesive has cured, the operator attaches the selected piston.
Then the operator pushes and holds the "RUN" button. A continuous load is then applied perpendicular to the pull-stub until failure occurs, or until a specified load is reached.
The PATTI® can be pressurized with CO2 cartridges to make it portable for field use. In the laboratory, nitrogen or any clean inert gas system providing at least 100 psig (up to 160 psig) can be used.
